Answer:

12.55

Step-by-step explanation:

To solve for area using circumference, use the formula:

[tex]a=\frac{c^{2} }{4\pi }[/tex]

where a=area and c=circumference

We know the circumference is 12.56, so

[tex]a=\frac{12.56^{2} }{4\pi }[/tex]

Once you plug this in and solve, you get 12.55 for the area.

Hope this helps! :]
